2018 Buick Enclave: How engineers made it larger, lighter, more sophisticated

Buick used the unveiling of the 2018 Enclave at the New York Auto Show to introduce its new range-topping Avenir sub-brand to the world. With fancier interior finishes and exterior details, it's Buick's latest effort to make itself a proper luxury brand (or perhaps re-establish itself as such). However, lost in the Avenir song and dance is the fact that the 2018 Buick Enclave is a (very) long-awaited all-new model regardless of the trim level one selects. Like the Chevrolet Traverse upon which it is based, the new Enclave is bigger than the vehicle it replaces but considerably lighter, by about 400 pounds. "We told every engineer, 'get your job done, but then take the weight out,'" said engineer Rick Spina as we hovered next to his larger yet lighter creation. His team therefore set about taking a little bit of weight out from just about everywhere, from using additional aluminum in the suspension to varying the thickness of the frame (thicker in places that needed to be stronger, thinner and therefore lighter in places that didn't). Only about 100 pounds came out of the body with the rest coming from elsewhere. Not only will the reduced weight improve fuel economy (Buick-estimated at 19 mpg combined with FWD versus 18 for the 2017 model) and presumably the old Enclave's rather ponderous handling, but it should only make things easier for the new powertrain: General Motors' now-familiar 3.6-liter V6 and its latest nine-speed automatic. With 302 horsepower and 260 pound-feet of torque, Buick says the new engine will need 7.2 seconds to reach 60 mph with FWD or 7.5 seconds with AWD. That's a second quicker than before. Besides acceleration, towing is also bumped up by 500 pounds to 5,000. For those models with all-wheel drive, the Enclave has the same basic system featured on range-topping versions of the Buick LaCrosse. Besides power being sent front and rear, it can also differ from right to left in the back, although Spina is quick to point out that capability is for traction-enhancing purposes rather than sporty, handling-enhancing torque-vectoring ones. Buick owners already appreciated the Enclave for its quietness so the engineers decided to take it that much further. This included altering the exhaust, improving body sealing (there are triple door seals), including active sound deadening and utilizing advanced materials that absorb sound as opposed to simply being thick, dense and heavy enough to keep it out.

Buick Encore, Chevy Trax reportedly dead after 2022

The Buick Encore will not get an encore, and the Chevrolet Trax is dead in its tracks. Separate unverified reports say the two crossovers, which are essentially identical underneath the sheetmetal, will retire at the end of the 2022 model year without being directly replaced. Citing anonymous sources, enthusiast website GM Authority wrote that production of the Encore and the Trax is scheduled to end in the third quarter of 2022. Both models are manufactured in Bupyeong-gu, South Korea, and General Motors will reportedly use the extra production capacity to build more examples of the Trailblazer, which outsold the Encore and the Trax combined by a significant margin in 2021. General Motors hasn't commented on the report, but we wouldn't be surprised if the end is indeed near for the Encore and the Trax. Buick released the Encore for the 2013 model year, and Chevrolet launched the Trax for 2015, but the model made its debut as the Opel Mokka in 2012. It's at the end of its life cycle, and sales figures reflect this: 20,072 units of the Encore were sold in America in 2021, a drop of 52% compared to 2020, while 42,590 examples of the Trax found a home, a 60% decline. It's further proof that Americans don't like small cars. Viewed in that light, the decision not to replace either crossover makes perfect sense. If the report is accurate, the Encore GX (which is not related to the Encore in any way) will enter the 2023 model year as Buick's entry-level model. The situation is a little more complicated at Chevrolet: The pocket-sized Spark is on its way out in 2022 as well, meaning that the Trailblazer will become the entry point into the range. It's a different story in Europe: Opel, which is now part of the Stellantis group, released the second-generation Mokka in June 2020.

Neil Young to auction model train collection, classic cars

LOS ANGELES — Rock singer Neil Young is selling some of his most prized possessions — part of his model train and classic car collections. The Canadian folk-rock star is putting more than 230 of his vast collection of Lionel trains and some of his cars up for auction in Los Angeles in December. Some of the trains have estimated selling prices of up to $9,000, Julien's Auctions said on Thursday. Young, 71, known for his Woodstock-era songs as well as "Ohio," "Heart of Gold" and many, many others, has been a passionate model train enthusiast for more than 20 years. His collection and vast layouts at his California ranch took off in the early 1990s as a means of connecting with his son Ben, who has cerebral palsy, Young said. Young is also selling some of his classic car collection. They include: A first-in-production 1953 Buick Roadmaster Skylark convertible 50th anniversary special edition, with a steering wheel hub saying "customized for Neil Young," that has a pre-auction estimate of $200,000 to $300,000. A 1954 Cadillac Fleetwood Imperial eight-passenger limousine (estimate $30,000-$40,000) with the Cadillac crest styled "Broken Arrow" emblem on the rear passenger door, referring to both the Buffalo Springfield song and his ranch of the same name in Portola Valley, Calif. A 1948 Buick Roadmaster Hearse built by Flxible (estimate: $8,000-$10,000) used by Young and his band, The Squires, to haul equipment to gigs in the early 1960's. Dubbed "Mortimer," it's decorated with backstage passes and bumper stickers, and it inspired Young's song "Long May You Run." A 1941 Chrysler Series 28 Windsor Highlander two-door, three-person coupe (estimate: $15,000-$20,000), considered Chrysler's most prestigious model in its day. (For a closer look at Young's lifetime interest in cars, here's a New York Times interview from 2012, which includes an anecdote about the time he ate road tar. Or his memoir "Special Deluxe: A Memoir of Life & Cars," in which he recounts every car he ever owned, and describes how he wrote the lyrics for "Like a Hurricane" in the back of a friend's 1950 DeSoto. He promoted the book in this NPR interview. He also tipped us off to the return of the Lincoln Continental, and is known for his LincVolt plug-in biodiesel 1960 Lincoln.) As for Young's train collection, he designed a remote control that allows multiple trains to run at once, and a device that delivers realistic railroad audio to help his son get the most of out the hobby.
